I have recently installed Firefox 2.0 on my computer and really appreciated its speed. Apart from some crashes after extensions upgrade, I noticed a clear enhancement in the browsing.
As I was reading a blog, I wanted to subscribe to its RSS feed. As I am using the Google Reader, I usually copy the link and then subscribe to it. With Firefox 2.0, just click on the RSS link and Firefox 2.0 will offer the option to add the feed directly to your favorite RSS reader. Very nice !!!
